Fehler: java.lang.NoClassDefFoundError Android

Question

Ich folge diesem tutorial to create swipe tabs. Aber ich bekomme den obigen Fehler.

Meine gradle Abhängigkeiten sturucture

dependencies { 
compile fileTree(dir: 'libs', include: ['*.jar']) 
testCompile 'junit:junit:4.12' 
compile 'com.android.support:appcompat-v7:23.1.1' 
compile 'com.android.support:design:22.2.0' 
} 

Hier meine Dateien sind. MainActivity.java

import android.support.design.widget.TabLayout; 
import android.support.v4.view.ViewPager; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.support.v7.widget.Toolbar; 
import android.view.Menu; 
import android.view.MenuItem; 

public class MainActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 


    TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout); 
    tabLayout.addTab(tabLayout.newTab().setText("Tab 1")); //this line gives error 
    tabLayout.addTab(tabLayout.newTab().setText("Tab 2")); //this line gives error 
    tabLayout.setTabGravity(TabLayout.GRAVITY_FILL); 

    final ViewPager viewPager = (ViewPager) findViewById(R.id.pager); 
    PageAdapter pageAdapter = new PageAdapter(getSupportFragmentManager()); 
    viewPager.setAdapter(pageAdapter); 
    viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout)); 
    tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() { 
     @Override 
     public void onTabSelected(TabLayout.Tab tab) { 
      viewPager.setCurrentItem(tab.getPosition()); 
     } 

     @Override 
     public void onTabUnselected(TabLayout.Tab tab) { 

     } 

     @Override 
     public void onTabReselected(TabLayout.Tab tab) { 

     } 
    }); 
} 

} 

Und meine PageAdapter.java Datei ist

import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentManager; 
import android.support.v4.app.FragmentStatePagerAdapter; 

public class PageAdapter extends FragmentStatePagerAdapter { 

    public PageAdapter(FragmentManager fm) { 
    super(fm); 
    } 

    @Override 
    public Fragment getItem(int position) { 

    switch (position) { 
     case 0: 
      return new InstaPicSwipeTab(); 
     case 1: 
      return new SongsDownloadSwipeTab(); 
    } 
    return null; 
} 

@Override 
public int getCount() { 
    return 2; 
} 
} 

Und das ist, was LogCat mir gibt

Wie um diesen Fehler zu lösen?

Answer 1

dies kommt, wenn eine Klasse zum Zeitpunkt der Kompilierung existiert, aber nicht zur Laufzeit, klicken Sie rechts auf dem app-open module settings gehen wählen dependencies Klick auf die + und wählen Sie ‚Bibliothek Abhängigkeit‘ wählen design und ok klicken, für gradle warten zu laufen , führe deine App erneut aus, bin mir sicher, dass das Problem behoben wird.

Ihr Top-Level-gradle muß, wie diese Bibliothek

apply plugin: 'com.android.application' 

android { 
compileSdkVersion 23 
buildToolsVersion '23.0.2' 

defaultConfig { 
    applicationId "aubry.chromio.com.dressup" 
    minSdkVersion 15 
    targetSdkVersion 23 
    versionCode 1 
    versionName "1.0" 

} 


dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    compile fileTree(dir: 'libs', include: ['*.java']) 
    compile fileTree(dir: 'libs', include: ['*.so']) 


    compile 'com.android.support:appcompat-v7:23.1.0' 
    compile 'com.android.support:design:23.1.0' 

} 

Answer 2

Die Version der Support-Bibliothek und Design aussehen soll gleich sein.

Ich änderte meine

compile 'com.android.support:appcompat-v7:23.1.1' 

zu

compile 'com.android.support:appcompat-v7:23.0.1' 

und Thema für mich festgelegt.

Hinweis: mein compileSdkVersion und buildToolVersion unter compileSdkVersion 23 buildToolsVersion "23.0.1"

Answer 3

Sie haben müssen gleiche appcompat und Design-Bibliotheken und auch 12.2.0 Version zu importieren.

Ich repariere es durch den Import dieser Bibliotheken.

compile 'com.android.support:appcompat-v7:25.2.0' 
compile 'com.android.support:design:25.2.0' 
compile 'com.android.support:recyclerview-v7:25.2.0' 
compile 'com.android.support:support-v4:25.2.0' 
compile 'com.android.support:cardview-v7:25.2.0' 

Answer 4

du nur noch hinzufügen: Kompilierung 'com.android.support:design:22.2.0' oder hohe Version: Kompilierung 'com.android.support:design:25.0.0' ist schön .

Unterstützung: Design hat Unterstützung enthalten: appcompat.
